RoC Retinol Correxion Deep Wrinkle Serum visibly reduces stubborn, deep wrinkles. This advanced serum, developed with dermatologists, uses RoC’s patented retinol, which is seven times more powerful. The lightweight formula targets wrinkles while restoring radiance for younger-looking skin. Dermatologists agree that retinol helps smooth deep-set wrinkles by supporting collagen and elastin. Safe for all skin types, it has a light, silky texture and is non-comedogenic and paraben-free.
